Transportation of large household appliances is always associated with risks, and the most vulnerable component in the refrigerator design is compressor. This unit is a heavy electric motor suspended on springs or shock absorbers inside a metal casing, which allows it to effectively dampen vibrations during operation. However, when moving equipment, these same springs become a source of danger, allowing the heavy motor to swing and cause crushing blows to the walls of the housing or pipelines.
Improper fixation or complete absence of fastenings during loading into a truck often leads to breakage of copper tubes, deformation of the housing, and even failure of the compressor itself. Owners often underestimate the inertial load that occurs when the car suddenly brakes or hits uneven roads, relying on standard bolts that are designed only to hold the weight static. To avoid costly repairs and refrigerant leaks, it is necessary to properly prepare the unit for travel using proven fixing methods.
There are several ways to secure the “heart” of your refrigerator, the choice of which depends on the design of the specific model and the tools available. In some cases, it is enough just to carefully pack the equipment, in others, partial disassembly and the use of additional spacers are required. Ignoring this stage can turn ordinary transportation into a disaster, so it is important to study the structure of your device in advance and prepare all the necessary materials.
⚠️ Attention: Any manipulations with the compressor that involve unscrewing fasteners or removing the casing should be carried out exclusively with the device disconnected from the network. Work should begin no earlier than 30 minutes after switching off, so that the refrigerant has time to flow into the condenser and the pressure in the system decreases.
Understanding the design of the compressor suspension
Before you begin mounting, you need to figure out exactly how the motor is secured inside your refrigerator. In most modern models, such as Indesit, Beko or LG, the compressor is suspended on three or four springs, which are attached at one end to the motor housing and at the other to the frame or casing walls. This shock-absorbing suspension ensures quiet operation, but creates a significant amplitude of free movement when shaking.
In older models or industrial refrigerators, you can find rigid fastening with bolts through rubber dampers. Here the risk of tube breakage is lower, but there is a possibility of loosening of threaded connections or damage to the rubber gaskets themselves. Understanding the type of suspension dictates the strategy of action: if you have a spring suspension, its stroke must be limited, and if a bolted one, check the tightness and fix the position.
What is the danger of unwinding springs during transportation?
If there is strong shaking, the springs can stretch to a critical state or, conversely, compress, which will lead to the metal casing hitting the walls of the refrigerator cameras. In the worst case, the suction or discharge tube may break off due to vibration, which will require complex repairs with soldering and refilling with freon.
It is also important to consider the location of the compressor. In classic models it is located at the bottom rear, but in some built-in or designer refrigerators it may be difficult to access, requiring removal of the rear panel. If you are not confident in your abilities or the design is too complex, it is better to turn to professionals, since careless handling of copper tubes can be fatal to the equipment.
Necessary tools and materials for fixation
To properly prepare the refrigerator for transportation, you will need a certain set of tools and consumables. You should not try to fix the compressor “by eye” or using improvised means such as adhesive tape or electrical tape - they will not withstand the load. You will need materials that can provide a rigid hold and protect surfaces from scratches.
The main element for creating spacers is often rigid foam, wooden blocks or thick rubber. These materials must be selected exactly to fit the gaps between the compressor and the casing walls. We also use fastening elements, such as tie belts or strong twine that will not stretch under load.
- 🛠️ Set of wrenches or heads - for loosening or tightening fastening bolts, if the design provides for the possibility of their adjustment.
- 📏 Tape measure or ruler - for accurate measurement of distances between compressor and internal walls to make an ideal spacer.
- 🧶 Strong rope, slings or tie straps — for fixing the position of the motor relative to the refrigerator frame.
- 📦 Sheets of thick cardboard, foam or felt —for laying between metal parts to prevent scratches and soften vibration.
Special attention should be paid to the choice of rope or slings. An ordinary clothesline can stretch and the fixation will loosen at the most inopportune moment. It is best to use polypropylene twine or specialized tying tapes with a ratcheting mechanism, which allow you to create the necessary tension. If you plan to use wooden blocks, make sure they are dry and free of cracks.
⚠️ Attention: It is strictly forbidden to use welding or gluing parts to the body to fix the compressor. Any intervention must be reversible and must not violate the integrity of the factory structures or the thermal insulation layer.
Fixation methods: dismantling or packaging
There are two main approaches to preparing the compressor: partial dismantling with rigid fixation and external packaging without opening the casing. The choice of method depends on how far you have to transport the refrigerator and on what roads. To move across the city in a soft-suspension truck, high-quality outer packaging is often sufficient.
The first method, rigid fixationinvolves creating a spacer that will prevent the compressor from moving inside the casing. To do this, measure the distance from the motor housing to the nearest casing wall at several points. Then a block of appropriate size is cut from wood or dense foam and inserted into the gap. This pin should not put pressure on tubes or electrical contacts; its task is to limit the travel of the springs.
The second method is external strapping. If the design of your refrigerator does not allow for the spacer to be inserted safely (for example, there is too little space or a complex piping configuration), you can use the external fixation method. The compressor compartment is tightly filled with soft but elastic material (foam chips, bubble wrap), and the refrigerator itself is securely fastened in the body.
Therefore, methods of internal and external fixation should be used in combination. Do not try to secure the compressor by simply wrapping it with wire - this may damage the insulation or compress the tubes.
Step-by-step instructions: how to make a spacer with your own hands
If you decide that internal fixation is necessary, follow these step-by-step instructions. This is the most reliable way to protect the motor from impacts against the casing walls. The process requires care and precision, since the space inside the compressor compartment is usually limited.
You must first remove the back panel of the refrigerator, if there is one, to gain full access to the compressor. Visually inspect the space around the motor, find points where the distance to the walls is maximum, but there are no tubes or wires. This is where the spacer element will be installed spacer.
☑️ Algorithm for installing the spacer
When making a spacer, keep in mind that it should not be too long so as not to create excess pressure on the springs in a quiet state. Its task is to activate only when swinging. Ideally, you can wedge the compressor housing itself against the refrigerator frame using V-shaped stops on both sides.
After installing the spacer, gently rock the refrigerator from side to side (without tilting it too much). You should feel that the inside has become “more silent”, the ringing metallic clang characteristic of a motor dangling on the springs has disappeared. If the sound remains, the spacer may be installed incorrectly or its dimensions are insufficient.
| Space material | Pros | Cons | Recommended application |
|---|---|---|---|
| Wood (bar) | High rigidity, reliability | Can scratch metal, requires precise adjustment | For long-term transportation over long distances |
| Dense foam | Lightness, shock absorption, does not scratch | Less durable, may crumble | For city travel and models with a tight casing |
| Rubber (automotive) | Excellent vibration damping | It is difficult to find a piece of the required hardness and shape | For filling small voids around the motor |
| Curled cardboard | Availability, softness | Low load-bearing capacity, can wrinkle | Only as an additional seal, not the main element |
Do not forget that after transportation the spacer must be removed. If you forget to do this and turn on the refrigerator with a rigid spacer installed, vibrations from the running motor will be transmitted to the entire body, which will lead to loud noise and possible destruction of the fastenings.
Transportation rules and external fastening
Even a compressor perfectly fixed from the inside requires correct external fixation of the refrigerator itself. The basic rule is: the equipment must be secured in such a way as to prevent any movement, tilting and impacts on the sides of the vehicle. The tilt of the refrigerator during transportation should not exceed 40 degrees, and ideally 20 degrees.
Use belts with tensioner to fix the case. Lay the belts through soft pads (blankets, cardboard) to avoid damaging the paintwork or plastic elements. The belt should pass through the strongest parts of the case, but in no case through the doors or glass shelves inside.
If you still had to transport the refrigerator lying down (which is extremely undesirable for a compressor with a pendulum suspension), make sure that it lies on the side opposite to the exit of the compressor tubes, or strictly on its back, if this is permitted by the manufacturer's instructions. In a horizontal position, the risk of damage to the compressor suspension increases many times, so the speed of movement should be minimal.
⚠️ Attention: After transportation in a horizontal position or with a strong tilt, the refrigerator should not be turned on immediately. It needs to stand upright in a warm room for 4 to 12 hours (depending on the time of lying) so that the oil flows back into the compressor and the refrigerant is distributed throughout the system.
Common mistakes when preparing to move
One of the most common mistakes is trying to secure the compressor by wrapping it with wire directly through the casing. This is a serious violation that can lead to deformation of thin-walled copper tubes and instant depressurization of the system. The wire can also damage the electrical insulation of the motor.
Another mistake is using soft, crushable materials as the only support. Rag bags or loose foam rubber will simply crumple under the weight of a heavy motor, and the compressor will continue to hit the walls. The spacer should be rigid or semi-rigid, retaining its shape under load.
Many people forget to check the condition of the fastenings themselves before the trip. If the suspension springs are already cracked or corroded, any shaking may be their last. In this case, transportation without preliminary repairs or reinforced fixation is almost guaranteed to lead to a break.
It is also dangerous to leave open access to the compressor compartment while driving. Dust, dirt, insects or accidentally dropped objects can damage the electrical part or the heated motor. Always install the protective panel in place before moving.
What should you do if, after transportation, the refrigerator hums more than usual?
An increased hum may indicate that the compressor has shifted during transportation and is now touching the casing or tubes. It is necessary to turn off the device, let it stand and check the gaps around the motor. It may be necessary to adjust the position or replace the shock absorbers.
FAQ: Frequently asked questions
Is it possible to transport a refrigerator with the compressor secured with factory bolts?
Some manufacturers supply refrigerators with transport bolts that rigidly fix the compressor. If your model has such bolts and they are installed, under no circumstances should they be unscrewed until the end of transportation. If there are no bolts, the standard fasteners are not designed for fixation during shaking.
Do you need to completely remove the compressor for transportation?
It is strictly not recommended to remove the compressor yourself. This requires bleeding the freon, unsoldering the tubes and subsequent evacuation and charging of the system. Such work can only be performed by specialists with a license and equipment.
How to understand that the compressor is damaged during transportation?
Signs of damage may be: a metallic clang or knocking sound when tilting the refrigerator, failure to start the motor (only a hum or click is heard), the appearance of oily spots under the refrigerator or a characteristic burning smell insulation.
How long should the refrigerator stand after transportation?
If the refrigerator was transported vertically without strong tilts, 2-3 hours is enough. If it was transported lying down or with a strong list, the standing time increases to 8-12 hours, especially in the cold season, in order to warm up and restore oil circulation.
